Notes:
1. The symbols used for timing specifications herein follow the pattern of t(First two letters of functional block)(signal)(state)
(reference)(state) for inputs and t(First two letters of functional block)(reference)(state)(signal)(state) for outputs. For example, tLBIXKH1
symbolizes local bus timing (LB) for the input (I) to go invalid (X) with respect to the time the tLBK clock reference (K) goes
high (H), in this case for clock one(1). Also, tLBKHOX symbolizes local bus timing (LB) for the tLBK clock reference (K) to go
high (H), with respect to the output (O) going invalid (X) or output hold time.
2. All timings are in reference to local bus clock for DLL bypass mode. Timings may be negative with respect to the local bus
clock because the actual launch and capture of signals is done with the internal launch/capture clock, which precedes LCLK
by tLBKHKT.
3. Maximum possible clock skew between a clock LCLK[m] and a relative clock LCLK[n]. Skew measured between
complementary signals at OVDD/2.
4. All signals are measured from OVDD/2 of the rising edge of local bus clock for DLL bypass mode to 0.4 × OVDD of the signal
in question for 3.3-V signaling levels.
5. Input timings are measured at the pin.
6. The value of tLBOTOT is defined as the sum of 1/2 or 1 ccb_clk cycle as programmed by LBCR[AHD], and the number of local
bus buffer delays used as programmed at power-on reset with configuration pins TSEC2_TXD[6:5].
7. For purposes of active/float timing measurements, the Hi-Z or off state is defined to be when the total current delivered
through the component pin is less than or equal to the leakage current specification.
8. Guaranteed by characterization.
9. Guaranteed by design.
